The present embodiment additionally provides a kind of display device, including above-mentioned array substrate.The knot of display device other parts Structure may be referred to the prior art, this is not described in detail herein.The display device can be:Liquid crystal panel, Electronic Paper, liquid crystal TV, liquid crystal display, Digital Frame, mobile phone, tablet computer etc. have the product or component of any display function.
Embodiment five
The array substrate of the present invention is described further below in conjunction with the accompanying drawings:
As shown in figure 3, in the manufacturing process of existing array substrate, before Source and drain metal level is deposited, array substrate it is non- Do not connected between the grid line 1 of display area and GOA unit 2, in such cases grid line 1 due to contact or other reasons introduce it is quiet Can not be discharged after electricity can generate charge accumulation.Semiconductor electric conductivity increases after being preheated before Source and drain metal level is deposited, mono- with GOA Capacitance, drive signal line 3 and a-si figures 4 are formed between the drive signal line 3 of 2 connection of member and parallel a-si figures 4 above The respectively lower substrate and upper substrate of capacitance, if what is accumulated on grid line 1 is positive charge, then according to the corresponding a- of capacity effect Si figures 4 assemble negative electrical charge, and the tip of grid line 1 and the tip of a-si figures 4 charge with opposed polarity respectively, work as charge at this time Point discharge both after accumulation to a certain extent causes ESD (Electro-static Driven Comb), i.e. GOA ESD in array substrate production process It is bad, affect the yields of array substrate.
To solve the above-mentioned problems, using semiconductor, electric conductivity increases this characteristic, such as Fig. 4 to the present embodiment at high temperature Shown in Fig. 5, in the non-display area of array substrate, semiconductor figure 6, semiconductor figure are formed on the insulating layer on grid line 1 Shape 6 is corresponding with the end 5 of grid line towards GOA unit 2, and at normal temperatures, the electric conductivity of semiconductor figure 6 is poor, although with The overlapping region in end 5 can also form capacitance, but the effect for carrying out capacitance charging is little.
When being preheated before depositing Source and drain metal level, the environment temperature residing for semiconductor figure 6 rises to 170 from room temperature Degrees centigrade, the electric conductivity of semiconductor figure 6 increase, and forming capacitance with the region that grid line end 5 overlaps can be effectively Capacitance charging is carried out, has the characteristics that voltage value is high and charge is less using electrostatic, according to voltage value=charge value/capacitance side Formula reduces voltage value, and the charge that grid line end 5 accumulates after voltage value reduces is difficult to that point discharge occurs, and reduces due to grid line GOA unit damage caused by end 5 is discharged improves the yields of array substrate.
Further, in order to strengthen the effect of capacitance charging, the width of grid line end 5 is more than the width of grid line other parts Degree, corresponding, the width of semiconductor figure 6 is also bigger, due to capacitance size be it is directly proportional with two capacity substrate areas, The size that capacitance is formed between grid line end 5 and semiconductor figure 6 can be so effectively increased.Preferably, the width of grid line end 5 Degree can be 2-10 times of the width of grid line other parts;The size of semiconductor figure 6 changes with the size of grid line end 5 and is changed Become, it is preferable that the size of semiconductor figure 6 is equal to the size of grid line end 5.
In addition, in order not to increase the number of the patterning processes of production array substrate, semiconductor figure 6 can be with array substrate The active layer of upper thin film transistor (TFT) is set with layer with material, and such semiconductor figure 6 can be with thin film transistor (TFT) on array substrate Active layer be formed simultaneously by a patterning processes, reduce the production cost of array substrate.Due to having for thin film transistor (TFT) Active layer is generally made of a-si, and therefore, semiconductor figure 6 can also be made of a-si.Certainly, if thin film transistor (TFT) Active layer is made of other materials, and correspondingly, semiconductor figure 6 is also using the same material of active layer with thin film transistor (TFT) It is made.
The present embodiment is illustrated by grid line citing of the first metal layer figure, certainly, the first metal layer figure not office It is limited to grid line, in the manufacturing process of array substrate, after the first metal layer figure is formed, before depositing second metal layer, all Semiconductor corresponding with the first metal layer figure end can be formed on insulating layer in non-display area on the first metal layer Figure, to discharge the electrostatic of the first metal layer figure end accumulation.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art For, without departing from the principles of the present invention, several improvements and modifications can also be made, these improvements and modifications It should be regarded as protection scope of the present invention.
